Abstract: A method for the control of a liquid crystal display that includes a matrix of pixels arranged in crossed lines and columns. A switching of state of the liquid crystal molecules, is controlled by application of an electrical control signal between two electrodes (50, 52) framing each pixel, generates a flow according to a particular direction (18), characterized in that, to control the switching of at least some of the pixels (P). The method includes applying to at least one neighboring pixel (58), according to the direction of flow, of a pixel (P) whose switching is controlled by the electrical control signal, auxiliary electrical signals whose amplitude is less than the anchorage breaking voltage and whose rising or falling edges are temporally placed in advance or in coincidence with the active falling edge of the electrical control signal, to favor the switching of the said pixel to be controlled (P).

Abstract: A method for addressing a bistable nematic matrix LCD having two stable textures without any applied electric field. Pixel addressing is of the passive multiplex type. The method includes selecting the value of the electrical voltage applied between the substrates so that an average value of the voltage, preferably the average quadratic value, since the initial command for image display up to the time immediately preceding switching, has a predetermined value independent of the information to be displayed, which is the same for all the pixels of the image.

Abstract: The present invention relates to a method of addressing a bistable matrix screen, in which the following two steps are reiterated: A. a disturbance signal is applied to each pixel of a marking area for a time t1, said disturbance signal being higher than a threshold signal such that each pixel of the area leaves its initial stable state, said disturbance signal being lower than a switching signal such that each pixel of the area having one of the stable states as its initial state does not switch into the other stable state, each pixel of the area then being in an intermediate disturbed state that is intermediate between the two stable states, and then B. no signal is applied to each pixel of the area for a time t2 to allow each pixel of the area to return to its initial stable state.
